We present our experience of diagnosing unilateral congenital dacryocystocele using HDlive Silhouette at 32 weeks and 6 days of gestation. A right congenital dacryocystocele was noted in a routine third-trimester fetal anomaly scan. HDlive Silhouette clearly showed the spatial relationships among the dacryocystocele, lens, eyeball, and optic nerve. This technique may provide additional information for the precise assessment of fetal orbital and periorbital anatomical structures.
